If the server hardware is really identical including disks of the same sizes,
the fastest way to roll them out is probably clonezilla, which has the big
advantage of being mostly agnostic toward the target OS. You can try it out
with the bootable iso, using sshfs or nfs to connect to network storage for the
image. If you like it, set up the drbl server to pxe boot into it. It is rpm
packaged, but I ended up using ubuntu on the server because it used to only use
the server's kernel on the clients and I needed something newer than Centos
provided for windows machines. Now I believe you can configure it to pxe boot
the image from a current livecd even if you run it on a different server.
Besides the ability to clone windows and other OS's, it also is good for
snapshot backups of systems (if you can take them down for the copy) and it
duplicates everything, including any local installs and config edits.
